Doomsayer

You become invisible at the same time that an illusory double of you appears where you are standing.  When you cast this spell you choose a point within 30ft and the illusory double moves there and then stops moving or taking actions. To your enemies, this movement provokes an attack of opportunity. The illusion's AC is equal to your spell save DC, and it has 0 hit points. This spell lasts until the illusion takes damage, you attack, or cast a spell, and always ends the end of your next turn.
